Do you know what the Welding process of brazed cold plate is? from Sanqian's blog

Do you know the welding process of brazed cold plate? Come and listen to the editor of the brazed cold plate manufacturer Changzhou Sanqian Technology Co., Ltd. tell you about it.

Friction stir welding of Brazed cold plateAdvantage

1. Not sensitive to oxides before welding;

2. The welding seam strength is good, such as: aluminum alloy 5A06, the performance of the welding seam and the base metal is consistent; aluminum alloy 6061/6063, the welding seam can reach more than 80% of the base metal performance;

3. No auxiliary materials are added during welding, which belongs to solid phase connection, with good weld strength and excellent reliability;

4. Repair welding can be carried out for defects after welding;

Disadvantage

1. The welding seam is contour welding, which will cause the cold plate to channel water and affect the heat dissipation performance;

2. Excessive welding seam span will affect the pressure resistance index of the cold plate;

Brazed cold plate gas shielded weldingAdvantage

1. Compared with vacuum brazing, the price is cheap;

2. The welding seam is in surface contact, the cold plate after welding is similar to the design index, and the pressure resistance performance is good;

3. Suitable for mass production.

Disadvantage

1. Oil and water must be removed before welding (strict requirements)

2. Poor welding can cause batch scrap;

3. Auxiliary materials need to be added during welding, and heat treatment is required after welding;

4. The joint of the weld should not vibrate, which can cause the weld to extend; it is not easy to repair the welding defect;

5. 3A21 and 6063 are commonly used as welding materials, and the welding cost of the same material increases.

Brazed cold plate vacuum brazingAdvantage

1. The weld quality is good; the quality is stable and reliable;

2. Compared with gas shielded welding, the welding quality of the same material is simple and the quality is good.

Disadvantage

The quality of the horizontal welding seam is stable, and the reliability of the longitudinal seam is poor. Gas shielded welding and vacuum brazing are actually equivalent to the middle and high configuration of a car. The pursuit of good welding quality requires more investment.
